The production of crops and meat needs a large area of land and other resources, such as water, chemical fertilizer and pesticides. Developing countries with highly dense populations have dramatically changed food composition from mostly crops to more meat and milk, which forced the adjustment and optimization of agricultural production structure to supply the demand caused by these dramatic changes. Fostering sustainable practices in agriculture is important to protect our earth’s natural resources while providing food security to the growing populations in developing countries such as China. For adapting to this adjustment, more scientific researches are needed to develop the necessary technology and practice. Sweet sorghum, a variant of sorghum, accumulates high amounts of sugar in the stem and has high amount of proteins in their leaves. It is known as the biggest biomass crop around the world. Ruminants are mammals with hooves and notably a specialized stomach digesting of all plant biomass and acquisition of nutrients from the fibrous tissues of plants rather than the more easily-digestible parts such as the seeds. This article suggests a new sustainable agriculture strategy: From sweet sorghum planting, ensiling to ruminant feeding. It also points out the bottlenecks of the current usage of sweet sorghum as silage forage and gives the strategy how to engineer the ideal silage sweet sorghum in the future by molecular marker-assisted breeding and genome editing technologies.
